SUPPORT FOR sourses.

SPECIFICATION forming part of Letters Patent No. 294,871, dated March 11, 1884.

Application filed October 6, 1383. (No model.)

o @ZZ whom, t may concern-.-

Be it known that I, JOHN C. HAAG, of Lansing, in the county of Ingham and State of Michigan, have invented new and useful Improvements in Supports for Steam-Boilers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

lThis invention relates to certain new and useful improvements in the construction of supports for steam-boilers, and is especially designed as an improvement upon Letters Patent granted to me September l2, 1882, for a similar invention.

The invention consists in the peculiar construction and arrangement of the parts, whereby the support for the boiler forms water and steam vspaces at the sides of the furnace and at the rear of the boiler, forn the purpose of giving a greater boiler capacity, or more capacity for making steam, without necessarily increasing the size of the boiler, all as more fully hereinafter set forth.

Figure l is a perspective View of my inrproved boiler-support, and Fig. Zvis a central vertical longitudinal section ofthe same.

In the accompanying drawings, which form a part of this specification, A represents the front wall of my improved boiler-support, which is preferably made of cast-iron, and which is provided with the usual doors to afford access to the grates.

The side walls, B, of my device are formed hollow, as shown, o f boiler-iron, being water and steam tight, and of a width preferably so that when in place their upper edges will be upon the same plane with the top. of the boiler. The front ends of these side walls or water-legs7 are' properly and rigidly secured by bolts to the fianges of the front wall, while their rear ends are likewise secured to the cast-iron plate C, to which latter is also secured the forward end of the semicircular flue D, which is constructed of sections e and j', substantially in the manner described in my hereinbefore-mentioned Letters Patent, with the exception that the rear end of the section f is formed double, so as to providev a steam and water tight compartment, a.

E represents in dotted outlines the boiler.

b is a feed-water pipe, through which water is introduced into the water-space a at the rear of the support, and from this space there is a pipe, d, which forms communication between this water-space and the boiler below the water-line.

lz, is another pipe, which affords communication from the top of this space c to the steam-space of the boiler.

F represents a series of pipes, the forward ends of which communicate with the waterlegs B, from whencethey extend back along the bottom of the semicircular flue D and communicate with the water-space a; and t' are pipes which connect the upper portions of the water-legs B to the steam-space of the boiler.

I design to fill in the space between the arch and circular Hue and the boiler with a layer of brick, so as to prevent the escape of heat from the furnace, which is located below the bottom plane of the fire-walls, as in the ordi- 'nary manner. A suitable breeching should be provided for covering the exposed end of the boiler. l

It will be seen that this support can readily and easily be taken apart and set up, and that by the addition of the water-legs or walls B and thc steam and water space a, I greatly in` crease the capacity of steam-making in my boiler, as there is a free circulation ofthe water between all the parts.

The location of the waterlleg in the rear of the boiler, as shown in my drawings, utilizes the heat which is usually wasted by passing up into the stack in that class of boilers where the water-leg is arranged directly in the rear of the furnace.

XVhat I claim as myinvention isl. A sectional support for boilers, consisting of the fire-box and combustion-chamber A, provided with'side water-legs, B, and a water-leg, a, arranged in the rear of the boiler proper, and all detachably secured together, substantially as set forth.

2. A support or arch for boilers, consisting of the castiron front A, side water-walls, B, pla-te D, and combustion-chamber C, and provided with suitable pipes for connecting the side water-'walls to the boiler, substantially as specified.

JOHN G. HAAG.
